- Synthesis, insecticidal activities, and molecular docking studies of 1,5-disubstituted-1,3,5-hexahydrotriazine-2-(N-nitro)imines
-
Figure represented. A series of novel neonicotinoids analogs were designed by modifying the pharmacophore of imidacloprid to 1,3,5-hexahydrotriazine conjugated to nitroimine (iNNO2) and introducing the phenyl or arylmethyl at the 5-position, and their insecticidal activities were evaluated. Introducing a heterocyclic methyl at 5-position increased the insecticidal activities, whereas other phenyl, phenylmethyl or phenylethyl substituents were unfavorable to activities. Molecular docking study was also performed to clarify the interactions of the most potent analog 1-((6-chloropyridin-3-yl)methyl)-5- (3-pyridylmethyl)-1,3,5-hexahydrotriazine-2-(N-nitro) imine (7s) with the target nicotinic acetylcholine receptor, which explained the structure-activity relationships observed in vitro, and revealed further possibilities for insecticide development.

- Steric hindrance as a key factor on proton transfer in the σ-adduct forming reactions of o-substituted anilines with 1,3,5-trinitrobenzene in dimethylsulfoxide
-
Kinetic and equilibrium studies are reported of the reactions of 1,3,5-trinitrobenzene (TNB) with a series of o-substituted anilines in dimethyl sulfoxide (DMSO) in the presence of 1,4-diazabicyclo[2.2.2.]octane (DABCO). The pKa values in DMSO for the aniline derivatives were measured using the proton-transfer equilibrium with 2,4-dinitrophenol. Kinetic studies are compatible with a two-step process involving initial nucleophilic attack on TNB by amine to give a zwitterionic intermediate which may transfer an acidic proton to DABCO to yield the anionic product. The results indicate steric hindrance to proton transfer in reactions involving 2,6-disubstituted anilines.
